321 stainless steel sheet is part of the austenitic stainless steel family. 321 is basically a 304 grade containing titanium stabilizers. 321 type is ideal for applications where heat is a concern. 321 can be used for applications up to 900°C, while 304 is typically used up to 500°C. 321 grade has excellent forming and welding characteristics. It does not polish well and therefore will not be used in decorative applications.TW stocks a variety of sizes of 321 stainless steel, certified to AMS 5510, ASTM A 240 and SA 666.
321 stainless steel sheet is commonly used in aerospace, thermal, electrical, and structural applications. 321 stainless steel is reinforced with titanium, an alloy that performs well in high-temperature environments and is resistant to cracking and corrosion. 321 sheet/plate stock is available in full size and custom-cut lengths. We produce 321 stainless steel sheets to specifications such as AMS 5510 and ASTM A240 and can customize all thicknesses, sizes, and dimensions.
